In such an embodiment, a horizontal joint may be used in place of the elbow joint 110. A central axis 191 extending through a center of the first end fitting 109 extends horizontally along the horizontal plane (e.g., the X-Y plane) and is parallel to a horizontal axis (e.g., the Y-axis).

The first end fitting 109 is coupled to the fluid end 104 through at least an elbow joint 110 and a flange 111.

The second end fitting 112 is coupled to the manifold block 113 through at least an angled joint 114, a valve 115, and an adapter 116. The fluid injection system 100 includes a plurality of clamp assemblies 117 that coupled components together. The present disclosure contemplates that angled joints may include one or more of L-shaped joints, elbow joints, solid blocks having an angled outer face, and/or angled end fittings. The angled end fittings may be integrally formed with end fittings of flexible hoses. In one example, the angled joint 114 includes a tee/ell connection. The angled joint 114 includes a turn that is within a range of 0 degrees to 90 degrees. In one embodiment, which can be combined with other embodiments, the turn of the angled joint 114 is 45 degrees or 90 degrees. In the implementation shown in FIG. 1A, the angled joint 114 includes a 90 degree turn.

The first end 107 of the second flexible hose 119 is coupled to a second fluid end 104 of the second pump 120. The first end fitting 109 of the first end 107 of the second flexible hose 119 is oriented vertically and perpendicularly to the horizontal plane (e.g., the X-Y plane). The first end fitting 109 is coupled to a piping assembly 121 mounted to the trailer 102 of the second pump 120. The piping assembly is coupled to the fluid end 104 of the second pump 120. The piping assembly 121 includes one or more of an angled joint 114, one or more pipe conduits 122, and/or elbow joints 123.

FIG. 2D is a schematic partial isometric front view of the fluid injection system 200 shown in FIG. 2A including the articulation arm device 225 in the deployed position 225B, according to one implementation.

The articulation arm device 225 is mounted to the trailer 102 using a base 229 coupled to the trailer 102. The articulation arm device 225 includes one or more pivot joints 226 (two are shown) coupled between two or more arms 227 (three are shown). The articulation arm device 225 also includes a pivot joint 226 coupled between the base 229 and a first arm 227. FIG. 2A illustrates the articulation arm device 225 in the storage position 225A, and the articulation arm device 225 in the deployed position 225B. The storage position 225A is for storage of the flexible hose 106, such as during transportation of the flexible hose 106 and the pump 201. The deployed position 225B is for deployment of the flexible hose 106, such as during use of the pump 101 to pump frac fluids into the pump manifold 105. In one embodiment, which can be combined with other embodiments, each of the pivot joints 226 is movable in one or more degrees of freedom, such as up to six degrees of freedom. In one embodiment, which can be combined with other embodiments, each of the pivot joints 226 is movable in six degrees of freedom including heaving, swaying, walking, yawing, pitching, and rolling.

The articulation arm device 225 also includes a connection device 228 coupled to an end arm 227 (a third arm 227) of the two or more arms 227. The connection device 228 is configured to connect to and support the second end 108 of the flexible hose 106. In the storage position 225A, the second end 108 of the flexible hose 106 is suspended from and supported by the connection device 228 of the articulation arm device 225. The connection device 228 grips the second end 108 and moves the second end 108 to couple the second end 108 to the pump manifold 105.

In one embodiment, which can be combined with other embodiments, the connection device 228 includes a clamp assembly that is configured to clamp to the second end 108 of the flexible hose 106. In one embodiment, which can be combined with other embodiments, the connection device 228 includes a pin assembly that is configured to pin the second end 108 of the flexible hose 106 to the connection device 228. The arms 227 are pivotable relative to the respective pivot joints 226 to which the respective arms 227 are coupled. Each of the pivot joints 226 may include a ball joint and/or a hinge plate. The pivot joints 226 may be locked to lock the articulation arm device 225 such that the arms 227 do not pivot relative to the pivot joints 226. In one example, each of the pivot joints 226 is locked during the storage position 225A of the articulation arm device 225. In one embodiment, which can be combined with other embodiments, the articulation arm device 225 includes one or more springs, one or more shock absorbers, and/or one or more actuators coupled to one or more of the arms 227. The actuators can be hydraulic, pneumatic, electric, mechanical, and/or any combination thereof for actuating the multi-point articulation arm device 225 to manipulate and/or support the flexible hose 106.

The one or more springs compress and/or decompress upon pivoting of one or more of the arms 227. The articulation arm device 225 includes an adjustable trolley that is movable along the base 229 to move the arms 227. In one example, a second arm 227 between the first arm 227 and the end arm 227 includes a spring that compresses and/or decompresses upon articulation of the articulation arm device 225. In one embodiment, which can be combined with other embodiments, the articulation arm device 225 balances forces acting on the arms 227 to place the second end 108 of the flexible hose 106 in a near zero gravity (“zero-g”) condition.

A disconnection device may be used to quickly disconnect the connection device 228 from the second end 108 of the flexible hose 106. The disconnection device may be hydraulic, electrical, pneumatic, or mechanical. In one embodiment, which can be combined with other embodiments, the disconnection device includes a hydraulic latch. The disconnection device can reduce the rig-up time to deploy the flexible hose 106 and reduce downtime for frac pumping operations.

The present disclosure discloses various methods. As an example, a method of deploying the pump 201 (a frac pump) mounted to the trailer 102. The method includes supporting the second end 108 of the flexible hose 106 on the end arm 227 of the articulation arm device 225. The method also includes moving the second end 108 of the flexible hose 106 above the manifold block 113 of the pump manifold 105. The moving the second end 108 of the flexible hose 106 includes articulating the articulation arm device 225 mounted to the trailer 102. The articulating the articulation arm device 225 includes pivoting two or more arms 227 of the articulation arm device 225 relative to one or more pivot joints 226 coupled between the two or more arms 227.

The method also includes coupling the second end 108 of the flexible hose 106 to the manifold block 113 of the pump manifold 105, and pumping a frac fluid from the fluid end 104 of the pump 201 and through the flexible hose 106 and into the pump manifold 105. The method also includes, after the coupling and prior to the pumping, disconnecting the end arm 227 of the articulation arm device 225 from the flexible hose 106.

FIG. 3A is a schematic partial isometric front view of a fluid injection system 300 including an articulation arm device 325 at a wellhead site, according to one implementation. In FIG. 3A, the articulation arm device 325 is in a storage position, a retracted position, and a lower position.

FIG. 3B is a schematic partial isometric front view of the fluid injection system 300 including the articulation arm device 325 shown in FIG. 3A, according to one implementation. In FIG. 3B, the articulation arm device 325 is in a deployed position, an extended position, and a raised position.

The articulation arm device 325 includes a base 329 mounted to the trailer 102, a vertical column 330, and a pair of bars 331 coupled between the base 329 and the vertical column 330. The articulation arm device 325 also includes an adjustable block 332 that is movable up and down along the vertical column 330. Each of the adjustable block 332 and the vertical column 330 includes pin openings for insertion of pins to lock the adjustable block 332 in place along the vertical column 330. The articulation arm device 325 includes one or more arms 327 (three are shown) coupled to the vertical column 330 through the adjustable block 332, and a connection device 328 coupled to an end arm 327 of the arms. The connection device 328 is similar to the connection device 228 shown in FIGS. 2A-2D, and includes one or more of the features, components, aspects, and/or properties thereof. The articulation arm device 325 also includes a plurality of hinge plates 326 (three are shown). The connection device 328 is coupled to the end arm 327 through one of the hinge plates 326. The connection device 328 is configured to connect to and support the second end 108 of the flexible hose 106.

The articulation arm device 325 includes a plurality of pairs of links 333 (six are shown). A first arm 327 is coupled to the vertical column 330 through one pair of links 333 coupled between the first arm 327 and the adjustable block 332. The articulation arm device 325 is movable up and down by, for example, moving the vertical column 330 up and down to move the arms 327 up and down (e.g., along the Z-axis). Moving the arms 327 up and down moves the second end 108 connected to the connection device 328 up and down. The second end 108 may be moved downward to couple the second end 108 to the manifold block 113 through the angled joint 114.

The articulation arm device 325 articulates horizontally (e.g., along the X-Y plane) to extend the arms 327 outward to move the second end 108 of the flexible hose 106. The articulation arm device 325 may be horizontally articulated manually, such as by an operator manually moving the connection device 328 and the second end 108 horizontally and above the angled joint 114 of the manifold block 113.

The flexible hose 106 includes a rotatable joint 335 that is at least part of a disconnection device that quickly disconnects the connection device 328 from the flexible hose 106. The rotatable joint 335 includes a ring disposed about the flexible hose 106. The disconnection device of the connection device 328 can disconnect the connection device 328 from the flexible hose 106 after the second end 108 is coupled to the angled joint 114, and the frac fluid may be subsequently pumped into the pump manifold 105. Disconnecting the connection device 328 from the flexible hose 106 facilitates reduced fatigue and increased operating life for the articulation arm device 325 as the articulating arm device 325 experiences less vibrations during frac operations.

FIG. 3C is a partial side schematic view of the fluid injection system 300 including the articulation arm device 325 shown in FIG. 3A, according to one implementation. The articulation arm device 325 includes an actuator 336 mounted to the trailer 102 and coupled to the vertical column 330. The actuator 336 may be powered electrically, hydraulically, pneumatically, or mechanically. The actuator 336, when actuated, vertically moves the vertical column 330 up and down to move the arms 227 up and down. The articulation arm device 325 is shown after the second end fitting 112 of the second end 108 is coupled to the angled joint 114 of the manifold block 113, before the connection device 328 is disconnected from the second end 108 of the flexible hose 106. After the connection device 328 is disconnected from the flexible hose 106, the articulation arm device 325 is retracted toward the trailer 102.

The present disclosure contemplates that the angle A1 of the first end fitting 109 is within a range of 30 degrees to 60 degrees, such as 40 degrees to 50 degrees. In one embodiment, which can be combined with other embodiments, the angle A1 is 45 degrees. The present disclosure also contemplates that other values may be used for the angle A1 in relation to the articulation arm device 325, such as 0 degrees or 90 degrees.

It is believed that, using aspects described herein (such as aspects of the articulation arm device 325), a single operator (e.g., a single human) may rig up and coupled the flexible hose 106 to the pump manifold 105 in less than 20 minutes (such as less than 10 minutes) to commence frac pump operations through the flexible hose 106.

FIG. 4A is a schematic partial side view of a fluid injection system 400 deployed at a wellhead site, according to one implementation. In the fluid injection system 400, the second end fitting 112 is removably coupled to a disconnection device 440 that quickly disconnects the second end 108 of the flexible hose 106 from the manifold block 113. The disconnection device 440 is coupled to the manifold block 113 through a valve 115. The valve 115 may be a swing valve, a check valve, a dart valve, or a plug valve. In one embodiment, which can be combined with other embodiments, the disconnection device 440 is remotely operable using a remote system to connect and disconnect the second end fitting 112 to and from the pump manifold 105. The disconnection device 440 is remotely operated from a remote structure 470, such as a data van, that is in communication with a controller 450 that actuates the disconnection device 440. A camera 480 provides a live image feed of the disconnection device 440 and the flexible hose 106 to an operator in the remote structure 470. In one example, the camera 480 is mounted to the bridge 503 of the overhead crane 501 (shown in FIG. 5). In one example, the camera 480 is mounted to a drone 490. In one embodiment, which can be combined with other embodiments, the disconnection device 440 includes robotics systems for remote operation and/or automated operation of the disconnection device 440. The disconnection device 440 facilitates connecting the flexible hose 106 to the pump manifold 105 and disconnecting the flexible hose 106 from the pump manifold 105 while the pump manifold 105 is under operating pressure supplied by frac pumps. In one embodiment, which can be combined with other embodiments, the robotics systems include a pre-programmed robot and a system including a feedback loop control. The feedback loop control can use sensors on the equipment (such as the disconnection device 440 and/or the flexible hose 106), and/or drone video feedback. In one embodiment, which can be combined with other embodiments, the disconnection device 440 includes a dry break coupling device. The disconnection device 440 can be mechanically actuated, pneumatically actuated, electrically actuated, and/or hydraulically actuated.

The implementation in FIG. 4A illustrates the valve 115 as vertically above the manifold block 113 and the disconnection device 440 vertically above the valve 115. The present disclosure contemplates that the valve 115 may be disposed horizontally to the left or right of the manifold block 113, and the disconnection device 440 may be disposed horizontally to the left or right of the valve 115.

Benefits of the present disclosure include at least quickly connecting flexible hoses to pump manifolds, ease of conducting maintenance, quickly conducting maintenance, ease of replacing assets, and quickly replacing assets, fracing continuously and on a 24/7 basis, increased operational efficiency, ease of installation, remote operation, reduction of iron assets required, and optimized flexible hose lengths and performance.

The flexible hoses used on high pressure equipment sides of frac pads can replace iron piping and reduce operating costs. Aspects of the present disclosure facilitate using flexible hoses between pumps and manifolds on a fleet production scale. Aspects of the present disclosure also facilitate preventing crushing of flexible hoses, and facilitate reducing bending moments of hoses. Additionally, aspects of the disclosure facilitate manipulating and moving flexible hoses when a crane cannot be used, such as when space constraints prevent use of a crane. Aspects also facilitate quickly making connections of flexible hoses and pumps to pump manifolds to quickly begin frac operations. Moreover, certain aspects of the present disclosure facilitate increased pumping time per day and the ability to frac all day and night without having to shut down the wellsite to remove a pump from service for maintenance or a failure while maintaining fracing on the well.

Aspects of the present disclosure include at least a hot stab remote connection/disconnection system that allows an operator to remove a connected iron/flex hose line from the pump to the manifold while the mainline is still under pressure. Aspects of the present disclosure also include a connection/disconnection device that includes a set screw, a mechanical latch, or some other quick connection device. The connection/disconnection device may be coupled to the second end of the hose. A vertical (non-horizontal) second end of a flexible hose is coupled to the manifold. Such aspects facilitating decreasing the bending load on the flexible hose end connections and also allows the flexible hose to be installed with a recommended single large radius bend which can work best in high pressure operation. In addition, the straight portions of the flexible hoses have negligible effect on how close a pump trailer can be to the manifold since the closeness is driven by the minimum bend radius of the flexible hose. If the flexible hose is too long for the application, the vertical orientation allows the additional length of flexible hose to just push farther up in the air and not cause any major additional crushing loads from a compound bend on the flexible hose body. Also, the effective remaining weight of the flexible hose to be overcome for installation on the manifold is much less influenced by the flexible hose taking some of the weight of the assembly and allowing for an easier installation for a typical frac hand operator.

It is contemplated that one or more of the aspects disclosed herein may be combined. Moreover, it is contemplated that one or more of these aspects may include some or all of the aforementioned benefits. As an example, it is contemplated that one or more aspects of the fluid injection system 100, the fluid injection system 200, the fluid injection system 300, fluid injection system 400, fluid injection system 500, the fluid injection system 600, the manifold device 700, the fluid injection system 810, the fluid injection system 910, the manifold device 1000, the fluid injection system 1010, the manifold device 1100, the fluid injection system 1210, the fluid injection system 1300, the fluid injection system 1500, the fluid injection system 1600, the fluid injection system 1700, the fluid injection system 1800, the fluid injection system 1900, and/or the fluid injection system 2000 may be combined.
